VALIDATION OF THE EXPERIMENTAL MODEL FOR INTERBODY BONE FUSION IN RATS

Purpose of this study is to develop and to assess surgical tactic of the instrumented interbody fusion modeling. 18 rats were selected and divided into two groups. In the first group anterior interbody fusion of the lumbar spine was performed and in the second group tail was instrumented. Experimental modeling of the lumbar spine results in death in all operated animals. Instrumented interbody fusion of the tail provides stable fixation during 4 weeks after surgery.
